SYNTHESIS AND VERIFICATION OF ADEQUACY OF DYNAMIC ELECTROMAGNETIC MODEL OF ASYNCHRONOUS ENGINE, WORKING IN THE CONDITIONS OF OFF-GRADE ELECTRIC POWER
Abstract:

A three-phase asynchronous engine is described with a shortcircuited rotor by the model made on the base of Park-Gorev’s equalizations and writtening relatively spatially - temporal complexes. Programmatic realization of mathematical analogue is approved by description of starting process, giving of loading and set mode of engine of type of MTKH by power 5,3 kW. The estimation of adequacy of mathematical model of electromechanics transformer is executed on results the conducted industrial experiment. The middle quadratics absolute and relative errors of prognosis, that testify to possibility of the use of model for the tasks of calculable researches of power efficiency of asynchronous engine, are expected. Drawn conclusion that the worked out mathematical analogue is the instrument of analysis of technique - economic indicators of work of electromechanics transformer in the conditions of changing indexes of quality of electric power.
